Application led July 8, 1901. Serial No. 67,505. (No model.) Y

To a/ZZ whom t may con/eerie:

Be it known that we, JAMES ASHFORD, a resident of 179 Aston road, and HERBERT EDWARD NEWEY, a resident of 54 Victoria street, in the city of Birmingham, England, subjects of the King of Great Britain, have invented new and useful Improvements in Photographic-Plate Holders, (for which we have made application for Letters Patent in Great Britain under No. 1,109, bearing date January 17, 1901,) of which the following is a specification.

i Our invention relates to improvements in photographic-plate holders; and the objects ofour'improvements are an improved envelop in which are incased the films or plates, a double-sided film or plate carrier; also, improved means in the holder for protecting the plates or films from light. We attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figure lis a front view of the plate or film carrier and envelop, part of the envelop being removedto show more clearly the carrier. Fig. 2 is a yertical sectional view of the carrier on line A B, Fig. 1. Fig. 3 is a vertical sectional view on line C I), Fig.A 1, showing also the envelop in position. Fig. 4 is a front view of the holder in which is mounted the plate-carrier. Fig. 5 is a side view of the holder, showing it partly open. Fig. 6 is a sectional plan view of the holder when closed on line E F, Fig.4, without the plate-carrier.

Fig. 7 is avertical sectional view ou line G H, Fig. 4', of the holder having the plate-carrier and envelop inclosed.

Similar characters refer to similar parts throughout the several Views.

10 is the carrier to receive the plates, iilms, or other sensitive surfaces, and inasmuch as either the one or the other may be used we shall refer to sensitive surfaces only. On each side of the carrier are flaps 11 11, consisting of an al1-round narrow edge, thus leaving the center open for sight. Between the carrier and the flaps are placed the sensitive surfaces for exposure. The upper end of the carrier is enlarged and provided with a continuous recess 12, whose surface is covered with velvet or other similar material 12.

13 is an envelop made of leather, paper, or

other suitable material, having its one end 14 closed and made light-tight, except its open end 15. This envelop is, made to receive the carrier 10, with its flaps and the sensitive surfaces, its open end passing into the recess 12, so that when thus placed the sensitive surfaces are perfectly protected lfrom light.

16 is the holder, having the usual ,exposureopening at its front and having the hinged door 17.

1S is a spring-pressed follower projecting from the dooi` 17 by the springs 19, so that it may yield to pressure as required. f

The interior of the holder is made to receive the complete carrier 10, with its envelop 13, the recess 2O being made to accommodate the enlargement at 20a on the one side, While the other side of the said enlargement 20a falls behind the end of the follower 18, as shown in Fig. 7. It will be seen that the envelop may now be withdrawn, and in so doing the carrier 10, with the sensitive surfaces, is retained in the holder. The front marginal surface of the follower 18 and the inside marginal surface around the exposure-Opeliing ofthe holder are covered with velvet or other similar material 2 l 22 to exclude light. The inner face of the holder and outerA face of the follower near their upper ends are recessed, as at 21 22,. so that the light-excluding surfaces at Itheir upper ends are set back somewhat to a depth a llittle more than the thickness of the sides ofthe envelop 13. Con

sequently as the said envelop is being withdrawn for exposure ere it quite leaves the holder it passes into therecessed portions 21 and 22, which are pressed against it by the springs 19, so as to exclude the light past such recessed portions 21 and 22; but as this takes place the front marginal surface of the follower 18 at 23 and the inside marginal surface at 2i have both closed lirmly onto the flaps 11 11, so that the light is perfectly shut off thereat ere the possibility takes place of light entering at the opening.

It will be readily understood that having used the one exposure the envelop is simply pushed back again over the carrier and seusitive surfaces, when the door may be opened and the envelop and carrier turned over, the door again closed, and the other sensitive IOO surface exposed. It will also be clear that our improved envelop may be used for single or double sided filrn-carriers.

Having thus described our invention, what We claim, and desire to secure by Letters Patent, is

l. The combination of a carrier having au enlarged head provided with a recess and adapted to carry the sensitive surfaces, and an envelop surrounding said carrier and adapted to have one end thereof engage in said recess.

2. VThe combination of a carrier having an enlarged head provided with a continuousrecess and adapted to carry the sensitive snrfaees, and an envelop surrounding said carrier and provided with a closed and an open end, said open end adapted to engage in said recess.

3. The combination of a carrier provided with flaps and having an enlarged head provided with a continuous recess, said flaps adapted to retain the sensitive surfaces within the frame, and an envelop surrounding said frame and provided with a closed and an open end, said open end adapted to engage in said recess.

et. The combination of aphotographic-plate holder, a door hinged thereto, a follower, and a spring interposed between and connected to 17, a spring-pressed follower 18, and a senstive-surface carrierl 10 having enlargements at one end engaging in a recess formed in said holder, substantially as set forth.

6. In combination, a photographic-plate holder provided with a light-excluding surface on its inner face surrounding the exposure-opening and with a recess, and a follower arranged in the holder and provided with a light-excluding surface and With a recess.

7. In combination, a photographic-.plate holder provided with a light-excluding surface on its inner face surrounding the exposure-opening and with recesses, one of which is adapted to receive the enlarged head of a sensitive-surface carrier, and a follower arranged in the holder Vand provided with a light-excluding surface and with a recess.
